Description

(#5679) - 175MB SAS RAID Enablement
Provides 175MB protected write cache to augment the performance and function of the embedded SAS disk controller in the system unit.
The daughter cards contain the RAID function and a 175MB of write cache. The auxiliary daughter card plugs into a special slot on the planar and provides battery power pack and redundant 175MB write cache memory for the daughter card. Concurrent maintenance of the RAID daughter card and the auxiliary daughter card is not supported. However, concurrent maintenance of the battery pack is supported. The daughter cards are installed in their own specific internal slots on the system unit backplane and do not require a PCI slot.
The #5679 adds RAID-5 and RAID-6 capability. A minimum of three disk units are required for a RAID-5 disk array, and a minimum of four disk units are required for a RAID-6 disk array.
The two-core 9408-M25 and the 9409-M50 can use a SAS DASD/Media Backplane #8345 in combination with FC #5679 to provide one external RAID enabled SAS port. One SAS EXP 12S disk drawer can be attached to this port and its disk drives controlled by the imbedded SAS disk controller. The one-core 9407-M15 does not support this attachment.
